Collation in Oracle 12cR2 gives some more finegrained possibilities for setting up how your data is to sorted and compared linguistically. A lot we could do before with NLS_SORT and NLS_COMP and the likes, but the collation features can both be simpler to use as well as offer more detailed control.

But do some testing for your specific language cases - you might find some small surprises like I did when trying it out with danish.
